Abstract
The utility model discloses a screw pump packing box with adjustable, reducible screw pump change the number of times of packing, extension screw pump well open the well time rate and screw pump life. The utility model discloses an adjusting gland and packing box body, adjusting gland and packing box body threaded connection, packing box body traditional chinese clothing has the compaction packing ring, and the regulating press is covered and is equipped with adjusting bolt. The utility model discloses can coordinate instrument commonly used, realize the incessantly inside compaction packing ring of well adjustment packing box, make its compaction packing, solve because of the packing box oil spilling problem that packing wearing and tearing, the increase of sealed clearance led to the fact, reduce the change and the opening of screw pump of packing and stop the number of times, pump period is examined to extension screw pump well, reduces the oil well operation expense, improves rate when opening the well.
Description
Technical field
The utility model relates to the packing box of petroleum industry producing well, particularly adjustable screw pump packing box, reduces screw pump and changes the number of times of packing, rate and service life of screw pump when extending the driving a well of screw bolt well.
Background technology
Screw pump production technique is widely used in each elephant, is a kind of oil recovery technique that mechanical oil recovery is conventional.Screw pump, when packing serious wear, will stop well in time, changes packing.This adds increased the number of times of start and stop well, cause the infringement to screw pump and polished rod, shorten application life, not only affect oil well output, too increase the management difficulty of screw bolt well.
Summary of the invention
The purpose of this utility model is to provide adjustable screw pump packing box, realizes not stopping well adjustment packing box and makes it seal, prevent oil spilling, extend the application life of screw pump, reduce the management difficulty of screw bolt well.
The utility model is achieved in that adjustable screw pump packing box comprises and regulates gland and packing box body, regulates gland to be threaded with packing box body, compacting packing ring is housed in packing box body, regulates on gland and adjusting bolt is housed.
The beneficial effects of the utility model are: the utility model can coordinate common tool, realize the compacting packing ring not stopping well adjustment packing box inside, make its compacting packing, solve the packing box oil spilling problem because packing wearing and tearing, seal clearance increase and cause, reduce the replacing of packing and the start-stop time of screw pump, extend screw bolt well pump detection period, reduce oil well operation expense, improve rate when driving a well.Can prevent screw pump packing box oil spill accident from occurring simultaneously, reduce screw bolt well conventional maintenance number of times, reduce management difficulty, there is good result of use and economic benefit.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing in detail the utility model is described in detail, see Fig. 1, adjustable screw pump packing box comprises adjustment gland 3 and packing box body 4, regulates gland 3 to be threaded with packing box body 4, compacting packing ring 2 is housed in packing box body 4, regulates on gland 3 and adjusting bolt 1 is housed.Compacting packing ring 2 is provided with centre bore, and the aperture of its centre bore is greater than the external diameter of polished rod 5, and the external diameter of compacting packing ring 2 conforms to the internal diameter of packing box body 4.Compacting packing ring 2 is at least provided with one, is arranged on above packing.The adjusting bolt 1 on gland 3 is regulated at least to be provided with
twoindividual, arrange in the middle part of the circle body of corresponding compacting packing ring 2, the top of adjusting bolt 1 is provided with spanner side.When after the packing wearing and tearing in packing box body 4, by the spanner side on adjusting bolt 1 top, rotate and be about to compacting packing ring 2 under adjusting bolt 1 makes it and press down compression packing, ensure the sealing effectiveness between packing and polished rod 5
,realize not stopping well and regulate packing box.Reduce the replacing number of times of packing and the start-stop time of screw pump, extend the application life of screw pump.
